I think you should be using the function in ChestGenHooks (ie: getItems or getOneItem) to ensure that chests in RogueLike dungeons remain relevant if lots of mods are installed. ExtraUtilities, RandomThings, Thaumcraft, Railcraft all add loot to chests. Getting sticks and bones and leather armor from RogueLike dungeons is pretty disappointing when "real" dungeon loot is so much better.

I already do use ChestGenHooks.
